Measuring Hydraulic Conductivity Using Geotechnical Centrifuge

The development of a small - scale geotechnical teaching centrifuge

Geotechnical engineering is a core discipline within civil engineering that supports the infrastructure development which underpins modern society. The simulation of realistic geotechnical design at undergraduate level is often restricted to routine calculation-based methods reinforced by simple element laboratory tests which fail to provide a holistic learning experience. Using the latest rese...

A method for measuring hydraulic conductivity and embolism in xylem

Hydraulic conductivity of the xylem is computed as the quotient of mass fiow rate and pressure gradient. Measurements on excised plant stems can be difficult to interpret because of timedependent reductions in fiow rate, and because of variable degrees of embolism. Using Acer saccharum Marsh, stems, we found that certain perfusing solutions including dilute fixatives (e.g. 0.05% formaldehyde) a...

Estimating Hydraulic Conductivity Using Pedotransfer Functions

Zoning hydraulic conductivity using different geostatistical methods (Case study Shavoor)

In studies of irrigation and drainage projects for drainage, it is necessary to extend the data from the sampling point to the network. Therefore, based on available data from observational wells, estimating the state of hydraulic conductivity (K) in the surrounding area. The estimation process values for locations where there is no information for them based on viewing areas called wells spati...

Measuring infiltration rate and hydraulic conductivity in a dry well in a thin overburden

IInfiltration rate and hydraulic conductivity are immensely important parameters for evaluating the hydrology of subsurface environments. Specifically, in disposal wells schemes and in artificial recharge plans both properties must be correctly assessed to better analyze the performance of these installations. In a new research, tanker water and rainfall runoff were injected into a 22.5 m deep ...
